Unplug and Clean Your Air Fryer
- Unplug the air fryer and allow it to cool completely before cleaning.
- Remove the basket and tray, and wash them with warm, soapy water to remove grease and food residue.
- Carefully inspect the heating element for any grease buildup or food debris. Wipe it gently with a damp cloth if necessary.
Check for Oil Leaks or Spills
Examine the bottom of the air fryer for signs of excess oil or spills. Oil leaks can cause smoke during operation. If you find leaks, clean the area thoroughly and consider replacing worn seals or gasket parts if applicable.
Inspect and Replace Components if Needed
Look for any signs of damage to internal parts, such as the heating element or wiring. If you notice any cracks, corrosion, or frayed wires, contact customer service or consider professional repair. Do not attempt to repair electrical components yourself if you’re unsure.
Use Correct Accessories and Liners
Ensure you’re using appropriate accessories, like the Cosori Air Fryer Liners, and avoid placing liners during preheating to prevent trapping grease and causing smoke. Use accessories that allow hot air circulation for even cooking and minimal residue buildup.
Perform a Test Run
- After cleaning and inspecting, run the air fryer at a high temperature (around 400°F) for 10 minutes without food to burn off any residual grease or manufacturing oils.
- Observe for smoke or unusual smells. If it runs clean, you can resume normal cooking.
